National Instruments CB-485A

The National Instruments CB-485A Terminal Block (Part Number: 778674-01) is engineered to facilitate 10-pin female RJ50 to 10-pin female screw terminal connectivity, making it ideal for RS-485 serial communication applications. This DIN-Rail mountable terminal block features a robust design, featuring a female RJ50 connector and ten screw terminals, and is constructed on a printed circuit board (PCB) within a specially designed enclosure. While the CB-485A offers some protection against electrical noise, it is not recommended for use in environments where signals may be significantly affected by electromagnetic interference. This terminal block is particularly well-suited for connecting local serial ports of the CFP-20xx Controllers and other peripherals, and RS-485 and RS-232 cables are available for separate purchase. With integrated options for ground connection and labeling, the CB-485A enhances organization within Compact FieldPoint systems. It is a low-cost, unshielded accessory that requires minimal installation effort and does not necessitate specialized tools, making it accessible for various applications. The CB-485A provides a practical solution for easily breaking out serial signals, allowing for customization of test systems in challenging environments while maintaining reliability.
